Go to Safe mode, log on to Administrator account.
Then go to users in Control panel and remove all the user passwords

OR uninstall the Adobe Reader from Safe Mode. Once done, install the FoxIt Reader which will do the same thing- read PDF files- without the clutter and problems of the Adobe Reader:
